Common Rodent Invaders and How to Protect Your Home

If there’s one unwelcome guest that no homeowner wants to entertain, it’s the common household rodent. They’re not just a nuisance; they pose a health hazard and can cause damage to your property. Here, at J&J Exterminating, we understand the importance of safeguarding your home against these uninvited critters.

You’re not alone if you find yourself waging an ongoing battle against rodents; these tough little animals have been perfecting the art of human cohabitation for centuries. But fear not, with a little knowledge and some proactive measures, you can significantly reduce the likelihood of a rodent infestation.

Identifying Your Furry Foes

Before you can defend your home, you need to know your enemy. In the United States, the most common indoor rodent invaders are the house mouse, the Norway rat, and the roof rat. Each of these rodents has its own unique habits and traits that can help you identify them.

House Mouse

The house mouse is the smallest of the trio, typically gray with a light belly. They are excellent climbers and can squeeze through incredibly small openings. Their droppings are spindle-shaped and about the size of a grain of rice.

Norway Rat

Bulkier and more robust, the Norway rat is usually brown with a lighter, cream-colored belly. They are good swimmers and are known to burrow. Their droppings are capsule-shaped and larger than those of the house mouse.

Roof Rat

Also known as the black rat, roof rats are agile climbers with long tails and large ears. They are typically black or dark brown with a lighter underside. Their droppings are spindle-shaped like those of the house mouse but are slightly larger.

The Hazards of a Rodent Infestation

Rodents aren’t just unsightly; they carry a range of diseases and pose health risks to your family. Hantavirus, salmonellosis, and even the bubonic plague are all potential hazards associated with rodent infestations. In addition to health risks, they can cause significant damage to your home’s structure, including gnawing through electrical wires, creating fire hazards.

Health Risks

Rodents can transmit diseases through their droppings, urine, and saliva. Contact with contaminated surfaces or inhalation of dust particles carrying these materials can lead to serious illness.

Property Damage

Chewed wires in attics and walls can cause electrical fires. Rodents are also known to damage insulation, which compromises energy efficiency, and will chew through just about anything to build their nests, from books to important documents.

Proactive Rodent-Proofing Strategies

The best way to deal with a rodent problem is to prevent it from happening in the first place. Here are some essential strategies to rodent-proof your home.

Seal Entry Points

Rodents are sneaky and can enter your home through the tiniest of openings. Inspect the exterior of your home for cracks, crevices, and gaps. Remember to check around windows, doors, pipes, and vents. Seal any openings with caulk or other appropriate materials.

Keep It Clean

A clean house is less attractive to rodents. Keep food tightly sealed and put away promptly, clean up spills and crumbs immediately, and don’t leave pet food out overnight. Regularly take out the trash and keep your yard free of debris and overgrown vegetation.


There are various deterrents that can help keep rodents at bay. Traps and baits can be effective, but be sure to place them out of reach of children and pets. Ultrasonic devices emit sound waves that are unpleasant to rodents but are generally harmless to humans and pets.

Professional Service

Sometimes, you may need to call in the professionals. A pest control service can conduct a thorough inspection of your property and advise on the best course of action. They can also help with more advanced prevention methods, such as installing exclusion devices and setting up ongoing monitoring.

Responding to an Infestation

Despite our best efforts, it’s still possible to have a rodent infestation. If you notice the signs (such as droppings, gnawed items, or sightings of the rodents themselves), it’s important to act quickly and strategically.

Identify the Problem

First, confirm the presence of rodents and determine the type. Look for signs like droppings, gnaw marks, nests, and the rodents themselves, or listen for the sounds of activity, which is often more noticeable at night.

Eliminate the Infestation

Traps and baits can be effective for eliminating a small infestation. For larger or more persistent problems, it’s best to call a professional. They have the expertise and tools to get rid of the rodents safely and effectively.

Sanitize and Repair

Once the rodents are gone, you’ll need to clean and disinfect the affected areas. This includes removing droppings, urine, and nesting materials, as well as repairing any damage. This will help prevent the spread of disease and discourage future infestations.

Final Thoughts

Rodent infestations are more than just a minor inconvenience. They can pose serious health risks and cause significant damage to your home. By understanding the threats, taking preventive measures, and promptly addressing any problems that arise, you can keep your home rodent-free and your family safe. Remember, when it comes to protecting your home, it’s always better to be proactive than reactive.
